Ralph owes the bank $86.25. He deposits $80.00 into his account. What is the current balance of Ralph's account?

Answer:

12

Step-by-step explanation:

distribute equation

-2 times k = -2k

-2 times -9 = 18

so -2k+18=-6

solve

subtract 18 from both sides

-2k= -24

divide -2 from both sides

k =12

Answer:

k=12

Step-by-step explanation:

-2(k-9)=-6

divide both sides

k-9=3

move the k to the right

k=3+9

add 3+9

k=12

by using distance formulae

Answer:

956300000000

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.  9.563  ×  10 ^11

The result can be shown in multiple forms.

Hi there! :)

a) (ii) The two angles are vertical angles, so they are congruent.

b)(i) y = 71°

  (ii) The two angles are alternate interior angles, so they are congruent.

c) z = 44°

(ii) m∠x = 65° because the two angles are vertical angles, so they are congruent.

b) (i)

∠y is an alternate interior angle, therefore:

m∠y = 71°

c) Use the sum of interior angles of a triangle to determine the measure of angle z:

180 = 65 + 71 + z

180 = 136 + z

180 - 136 = z

z = 44°.

Length side is 3 cm

Step-by-step explanation:

the length in square is called side.

A= sides X sides

9 = s^2

S= 3

Hope it helps.

Value of side length is 3 cm

Give that;

Area of square = 9 cm²

FInd:

Value of side length

Computation:

We know that,

⇒ Area of square = Side²

BY putting value into formula

⇒ Side² = 9

⇒ Side² = 3²

⇒ Side = 3

So,

Value of side length = 3 cm

Step-by-step explanation:

To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.

To help: draw vertical lines through each graph.

In graph W: the line would pass through the top and bottom of the circle - not a function

In graph X: the line passes once through every area - a function

In graph Y: the line passes through the top curve as well as the bottom curve - not a function

In graph Z: the line passes through the curves multiple times - not a function
